So guys, I received a good idea from one of the readers about including the Entertainment District arc in the book. I didn't mention when or where Hinatsuru, Suma, and Makio had died. Thus, adding this arc won't cause any conflict.
So just imagine this, okay. Both Daki and Gyutaro managed to survive by finding a way to escape before they get decapitated. Y/N and the LMK group finds about this and sends her husbands to investigate, but they disappear. Thus, out wonderful trio, Mk, Redson, and Mei join the adventure. I might make it seem like Y/N had already met Daki but somewhere else and she seeks vengeance for her deceased husbands.
So, do you agree to have this idea included in the book? You can share some of your ideas if you want to.
